Abstract
An easily tunable high frequency balanced transconductor without internal nodes and with a low output conductance is presented. The structure uses only 7 MOS transistors. The output conductance can be independently adjusted (in order to be canceled) without affecting the transconductance. The transconductor also guarantees the common-mode stability of balanced filter structures. The simulation results of a 5th order elliptic low-pass filter, using standard CMOS 2 μm process, at 100 MHz with Q and frequency controls are shown
